For reaction system given below, volume is suddenly reduced to half of its value by increasing the pressure on it. If the reaction is of first order with respect to O2 and second order with respect to NO, what will be the change in the rate of reaction? 2NO(g)+O2(g)2NO2(g)R={NO]2[0] A- Diminish to one-fourth of its initial value. B.) Diminish to one-eight of its initial value. e- Increase to eight times of its initial value. D- Increase to four times of its initial value
